Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Specific Implementation
[0026] This embodiment is an ultra-miniature high-temperature resistant button-type supercapacitor.
[0027] like Figures 1-4 As shown, a connecting post 2 is provided on the lower side of the positive electrode shell 1, and a heat sink 3 is provided on the outer side of the connecting post 2. The heat sink 3 is arranged in an array, and heat dissipation holes 4 are provided inside the heat sink 3. The heat dissipation holes 4 are arranged in an array. The upper side of the heat sink 3 is tightly attached to the lower side of the positive electrode shell 1. A thermal pad 5 is provided on the lower inner side of the positive electrode shell 1. A diaphragm 6 is provided in the middle of the inner side of the positive electrode shell 1. The positive electrode shell 1 is slidably connected to the negative electrode cover 7. A connecting piece 9 is provided on the lower side of the negative electrode cover 7. The connecting pieces 9 are arranged in an array. An adjustment port 10 is provided on the side of the connecting piece 9. A rubber ring 8 is provided at the connection between the connecting piece 9 and the positive electrode shell 1.
[0028] It should be noted that the electrolyte solution is usually encapsulated inside the battery, forming the core part of the battery together with the positive and negative electrodes and the separator 6. The separator 6 is located between the positive electrode shell 1 and the negative electrode cover 7. Its main function is to prevent the positive and negative electrodes from directly contacting each other and short-circuiting, while allowing electrolyte ions to move freely between the two electrodes, thereby maintaining the charging and discharging process of the battery.
[0029] The positive electrode shell 1 is the electrode in the battery where the oxidation reaction occurs. It is usually composed of a positive electrode sheet made of positive electrode material, and the positive electrode sheet is located on the inner side of the positive electrode shell 1. The negative electrode cover 7 is the electrode in the battery where the reduction reaction occurs. It is composed of a negative electrode sheet made of negative electrode material, and the negative electrode sheet is located on the inner side of the negative electrode cover 7. In addition, the outer shells of the positive electrode shell 1 and the negative electrode cover 7 are usually made of metal and are divided into a positive electrode shell and a negative electrode shell. They not only provide mechanical support and protection for the battery, but also serve as the positive and negative electrode leads of the battery.
[0030] like Figure 1 and Figure 2As shown, when connecting, the battery material is placed inside the positive shell 1, then part of the connecting piece 9 is placed inside the positive shell 1, then the remaining connecting piece 9 is bent, and then the connecting piece 9 is placed inside the positive shell 1. The adjusting hole 10 in the connecting piece 9 allows the connecting piece 9 to be effectively bent. When the connecting piece 9 loses force, the lower side of the connecting piece 9 will return to its original state. At this time, the negative cover 7 is connected to the positive shell 1 through the connecting piece 9, and the connecting piece 9 is tightly attached to the rubber ring 8, which plays a sealing role, so that the positive shell 1 and the negative cover 7 are tightly connected together.
[0031] As shown in Figure 1 and Figure 3 As shown, the lower side of the positive shell 1 is provided with a connecting column 2 and a cooling fin 3. The cooling fin 3 can increase the contact area of the positive shell 1 with air, thereby facilitating heat dissipation. In addition, the cooling fin 3 is further provided with a cooling hole 4 in the inside, which further increases the contact area of the cooling fin 3 with air, further enhances heat dissipation, and further achieves high temperature resistance.
